WHEEL-RIM-LOCKNG DEVICE.

Application ledAugust 5, 1925.A Serial No. 48,254.`

1 5 inventionf- Fig. 1 is a cross section on the line 1 1 of Fig. 2, showing my improved wheel rim locking device applied to a resilient wheel of usual type.

29 Fig. 2 is a side elevation Vof the same.

' Fig. 3 is a perspective view of the yoke and some of the parts connected therewith.

Figyi is a perspective'view of the felly bolt and the nut shown detached fromthe bolt; e e

Similar reference characters designateA similar parts'in the different views.-

' 1 designates a metal channel felly of usual type adapted to support on its periphery a rim 2 of ordinary type,-having mounted thereon the usual pneumatic tire 8. The felly 1 has vthe usual annular flange 4 which engages the rim 2 for holding the rim from lateral movement on thev felly in one direction. r

5 designates an ordinary clamping mem-. ber which bears against the adjacent side kof the felly 1, and is adapted to engage the rim 2 to hold it from lateral movementy in the other direction.

A transverse bolt 6 extends through holes provided in the felly 1 and throughr a hole provided inthe clamping member 5. head of the bolt comprising an annular lustrates the preferred embodiment of my,

TheV

ilange 7 bears against` the adjacent side of 6 and nut 8 adapted to hold thelatter from being turned. Such means comprises a locking member which may be a'yoke 9 having two arms 10 and 11 adapted, in the locking position to be disposed respectively at oppo` site sides of the felly 1 and to respectively engage the bolt 6 andfnut 8. j

The arm 10 is provided with a lateral y notch 12 which is adapted to receive the reduced outer end of the head of the bolt'G. The arm 11 is provided with a perforation 18, which is other than round, and which isv adapted to receive the nut 8 and toI engage the polygonal periphery thereofl to hold thenut from turning. The perforation 13 flares outwardly, and the nut 8 is loosely fitted therein, so that the yoke 9 may be swung to l release the arm 10 from the bolt 6, and then swung to clear the felly 1, when the yoke'9 is to be detached;

In the body of the yoke9 intermediate of the arms 10 and 11 provided a radial hole 18', in which is rigidly secured in any mauner a lock casingf14, in which is radially movable with an ordinary key, not shown, abolt 15, which in they locked position is f adapted to enter a radial hole 16 which is provided in the felly 1 intermediate of its flanges.

v1When the bolt"15 is in the locking position in the hole 16, as shown in Figs. 1 and 2, the yoke 9 will have its arms 10 and 11 engaged with the kbolt 6 and nut 8 respectively, and the yoke can not be moved from the lockingposition, until the bolt 15 is retracted with the key.' The rim 2 can, therefore, not be removed unless the nut 8 is freed from the arm 11, and this can only be eected by unlocking the lock and swinging the yoke 9 laterally and 4then inwardly atthe end yhaving the arm 10.

To prevent the yoke from rattling against the felly, a bow spring 17 has one end rigid,- ly fastened to the yoke 9 intermediate of the l.arms 10 and 11on the side of the yoke next adjacent the vfelly 1. The spring bears` against vthe felly 1 and, at itsrfree end,

against the yoke 9, thus yieldingly holding the yokefrom vibration. The spring 17 has a hole 18 through which the bolt .15: may

Dass. y f.

l In the operation of the invention, the rim 2 having been mounted on the'felly 1 and held thereon in vthe operative position by the bolt 6 and nut 8 engaging the felly and clampingl member 5 respectively, the. arm

lil

11 is made to receive the nut 8, and the arm 10 is positionedl so that the adjacent end ot the bolt 6 Will enter the notch 12, the loose fitting ot the nut in the arm perforation 13 enabling such positioning ot the yoke.

The key is then used to torce the bolt 15 to the locking position in which it will enter the hole 16 in the telly 1. The spring 17 will be held compressed. The yoke can not noW be released tromthe bolt 6 and nut 8, so that the nut can not be unscrcwed to release the clamping member 5.

To prevent dirt entering the hole 1S in which the casing la is mounted, the yoke may be provided with an externally threaded portion around said holey on which is removably litted a screw cap 19.

. One ot my locking devices yon a Wheel will prevent the unauthorized removall ot a rim trom the Wheel Without the use ot a proper key unless breakage ot the parts, 0r picking ot the lock is resorted to, and such consumes time, and is liable to attract attention. It desired, more than one ot the locking devices may be applied to a single Wheel.

I do not limit my invention to the structure shown and described, as many ineditications, Within the scope ot the appended claims, may be made, Without departing trom the spirit ot my invention.

Vhat I claim isz- 1. In a. Wheel rim locking device, a telly adapted to support a rim, a clampingmember bearing against the telly and adapted to engage and hold the rim trom lateral movement in one direction on the telly, a bolt eX- tending through the telly and clamping member and bearing against the telly, a nut on said bolt bearing against the clamping member, a locking member movable to and trom a position in which it Will engage the bolt and nnt and hold the latter trom turning, and a lock having a casing carried by the locking member and having a bolt adapted to be moved by a key' to and trom engagement With the telly tor holding the locking member trom moving trom said position.
